WINDOW LOCK.

Application filed March 9, 1923, Serial No. 624,022. VRenewed September10, 1925.

To @ZZ/whom t may concern:

Be it known that JOS ABELLA and J MORA, subjects of the King of Spain,respectively, residing at New York, respectively, in the county of N ewYork and State of New York, have invented certain new and usefulImprovements in lilindow Loc-lis, of which the following is aspecification.

This invention relates generally toL window fastening means, beingintendedfor application to the usual type of window having verticallymovable sashes, the invention having for an Object to provide a noveland simple forni of locking device for the sashes which will permit ofthe latter being locked in partially opened position.

For further comprehension of the invention, and of'the'objects andadvantages there of, reference will be had to the following oescriptionand accompanying drawings and to the appended claim in which the variousnovel features of the invention are more particularly set forth.

Fig. 1 of the drawings is an inside face view showing the device inposition on a window.

Fig. 2 is an enlarged transverse vertical section on the line 2-2 ofFig. 1.

vFigs. 3, 4l and 5 are detail perspective views of the various elementsof the locking device.

Fig. 6 is a fragmentary view, of similar nature to Fig. 2, but showing amodification. l

As here embodied our improved window locking device comprises a pair ofbrackets one of which is mounted on the top horizontal member of theupper sash and the lower on the corresponding member of the lower sash,and a rigid rod extending between said brackets. In the drawings theupper sash is indicated at 10 and the lower sash at 11.

The bracket on the upper sash comprises a circular block 12 which litsagainst the face of the sash and may be secured thereto by suitablemeans such as the screw 13 talring through. a central aperture in theblock. To hold the latter securely against rotation a key 14 may bepassed through a groove 15 in the wall of the block and into the sash.Extending diametrically across the outer face of this block arehorizontal and vertical grooves 16 and 17 respectively whereby theT-shaped head of the rod above referred to may be connected with theblock. This 'a substantially rectangular block 25 having lugs 26 onopposite sides through which fastening screws are passed to secure it tothe sash. Extending through this block from -top to bottoml is a bayonetslot 2T which opens through one side of the block.v this slot being ofsuliicient size to accommodate the lower end of the rod 20, which ispassed therethrough. To lock the rod to the block avscrew`28 is threadedthrough the front wall of the latter and is adapted to engage in theselected one of a number of longitudinally spaced sockets 29 formed inthe front face of the rod. .The screw 23 Amay have a suitably formedhead 30 thereon for manual manipulation7 while the lower end of the rod20 is outturned and provided with a knob 31, which ma7 be grasped whenthe upper sash is to be raised or lowered.

To insert the head of the rod 2O into the groove 16 in the bloclr therod must be held in a position with its main length approximatelyhorizontal and the bar 21 having its larger diameter alined with thegroove. After the bar has reached the bottoni of the groove the rod isswung downward and its head 21 is retained against outward displacementby reason of the cross sectional formation of the bar and groove.

In Fig. 6 we have` indicated a modified arrangement of the upper end ofthe rod adapted to permit of more, ready insertion of the head of therodA in the top bracket. In this construction the block 12 has a T-groove 35 therein adapted to receive the end of a T-bar 36 pivoted as at37 in the upper end of the rod 20. Projecting from the head of thisT-bar is a stud 38 which engages in an arcuate recess 39 cut into thebottom of the groove35. Slidably longitudinally in the shank of theT-bar 36 is a pin Ll() which is adapted to engage in a socket 40 in theend of the rod. This pin is urged against the top of the rod by means ofan expansion spring 41 coiled around the pin socket 40, when the pinsnaps into the socket and locks the T-bar to the rod, and in the samegeneral relation to the latter that the inclined portion assumes asy inFig. 2.

As will be understood, the ready removability and replaceability of therod 2O is an important feature. The rod can be removed from and replacedin the lower bracket through the bayonet slot 27. With the constructionshown in Figs. 1 to 5, to replace the rod in the top bracket the uppersash must be lowered, or the person replacing the rod must stand on achair or the like, while with the device illustrated in Fig. 6 it isonly necessary to pull the pin Ll0 Afrom the socket 40 by grasping thecol lar l2, and then swing the T-bar to the position shown, to permit ofreplacing of the rod.

ll/Thile we have shown and described a preferred embodiment of ourimproved window lock it is to be understood that we do not limitourselves to the precise construction herein disclosed and the right isreserved to placing the circular block l2 within the upper sash and toall changes and modifications made within the scope ot the invention, asdefined in the appended claim.

Having thus described our invention what we claim as new and desire toprotect by Letters Patent of the United States is as follows:

A window fastener comprising brackets adapted tor iixing on the upperand lower sashes of the window7 and a rod adapted to beremovably engagedwith each of said brackets, the upper bracket having a T* groovetherein, and the rod having a T- bar pivoted to its upper end andadapted to engage in said groove, said T-bar being adapted to be swungat right angles to the rod for insertion in said groove, and pin andsocket elements adapted to automatically engage as the lbar swings fromits said position to lock the T-bar against movement on said rod andmeans for locking the said rod to the lower bracket.

ln testimony whereof we have aiiixed our signatures.

JOS ABELLA. J OSE MORA.
